The problem

Since updating to 2024.3.0 the only snmp sensor entry i have will update for a variable amount of time before stopping. only a reboot of HA core gets it to update again.

I have attempted to increase logging but do not see anything else specific in the logs.

core-2024.3.0

What was the last working version of Home Assistant Core?

core-2024.2.4

What type of installation are you running?

I am also experiencing issues with SNMP not refreshing since updating to 2024.3. I was previously on 2024.1 and SNMP was working without issue.

[sphen13]

wondering if #112795 resolves....

agreed, get errors showing update interval timeout on more than just this intergration. Anything with update intervals less than 10 seconds fails. I use 45 second update intervals on checkmk with no negatives for the things i monitor in SNMP. Anyway to adjust this interval? If I restart HA I can get updates for a few minutes before failing.

After updating to 2024.3.0, SNMP took 2 times longer to start when the printer was turned off, it was about 100s, now it’s 200+

I am also experiencing SNMP issues after 2024.3.0 update.

It might for the sensor, but it times out for the device_tracker. See #110100 (comment)

same issue with 2024.3.0

Same issue here with 2024.3.0 and just now tested with 2024.3.1
I rolled back to 2024.2.5 and that fixes it for me.

The weird thing is, I don´t see anything in the logs.

[mapetster]

Fixed with 2024.3.1. For now.

yeah let us know how it goes as it would owrk for awhile until it stops. i have not tried 2024.3.1 yet - but looking at the changelog they did bump pysnmp-lextudio from 6.0.2 to 6.0.9

You might want to check #113457 for another known issue related.

yep looks to be the same issue :/

[lextm]

#113457 was resolved, but #113605 remains which requires #112815 to be merged.

After that I think this one can be closed as well.

[sphen13]

yeah the specific issue i had when bringing this up (snmp sensor update) seems to be resolved. i feel we could close this as the device tracking issues remain open.

snmp sensor updates resolved in 2024.3.1
